It routes one of two 4-bit data sources onto a single output bus, a common pattern in address decoding, data-path steering, and register-file readback for 5V logic systems. The 16-SOIC package fits surface-mount assemblies where through-hole 74LS parts are being retired. ## Output drive and fan-out High-level output current is 400 µA, low-level sinks 8 mA. That 8 mA sink is enough to drive one or two standard LS TTL loads but not a relay coil, LED indicator, or a long backplane trace without a buffer. Plan a line driver or pull-up resistor if the output must drive more than a few milliamperes. ## Lifecycle and sourcing The SN74LS158DR carries an Active lifecycle status with ROHS3 compliance.","metaTitle":"SN74LS158DR 74LS Multiplexer, 4 x 2:1, 16-SOIC","metaDescription":"TI SN74LS158DR 74LS quad 2:1 multiplexer, 4.75V-5.25V supply, 0°C to 70°C, 16-SOIC.
